WeWork is piloting a 3D printing program in Houston and four other cities.

The co-working company is partnering with 3D fabrication companies Formlabs and Glowforge through its WeWork Labs incubator to offer the service to entrepreneurs. Entrepreneurs must provide their material of choice.

"Partnering with Glowforge and Formlabs will give our members even more of an opportunity to take their ideas, and bring them to life," Katie Perkins, creative director of WeWork Labs, said in a statement.

Somerville, Mass.-based Formlabs will provide its Form 2 printer to help entrepreneurs scale their prototyping and production through desktop stereolithography, an additive manufacturing processthat uses a light source (laser or projector) to cure liquid resin into hardened plastic.

Seattle-based Glowforge is providing its Glowforge Plus 3D laser printer that uses subtractive laser technology. Unlike additive manufacturing, which builds up material layer by layer, subtractive manufacturing allows users to place their material (wood, leather, acrylic, stone, etc.) into the machine and carve out or engrave the product using laser light.
